Introduction
The contributors to this senior design project were Nathan DeLaRosa, Ashton Knecht, Jack Son, and Jerry Xia under the supervision of Dr. Jonathan Valvano.
This project aims to create a custom, low-cost interface for a Swan-Ganz heart catheter, bypassing the need for expensive cardiac output computers. The catheters intended to be interfaced are the part number needed produced by Edwards Lifescience. These catheters interface the part number needed pressure transducer, also made by Edwards Lifescience.
The project is split into three sections: the interface hardware, MSPM0 firmware, and the desktop application software. Details about each of these sections can be found in their distinct README files.

Questions
How big is the SwanGanzInterface V1.1 PCB?
It measures 193 × 114.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the SwanGanzInterface V1.1 use?
154 parts, built around the OPA2350UA, INA122P, FT232RNL and LM4041CILPR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the SwanGanzInterface V1.1 KiCad files?
From the ATK-1/SeniorDesign_SwanGanz repository on GitHub, at the commit this page was made from: the board is hardware/SwanGanzInterface_V1.1/SwanGanzInterface_V1.1.kicad_pcb and its schematic hardware/SwanGanzInterface/SGI_Power.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SwanGanzInterface V1.1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ATK-1 before reusing the design.
